Cross-Modal Transfer as a Window Into the Investigation of Recent Stimulus and Response History in Perceptual...

Area of Science:

• Cognitive Neuroscience
• Sensory Processing
• Perception

Background:

• Perceptual decisions are influenced by recent stimulus and response history.
• The origins and mechanisms of these history effects are not fully understood.
• Existing research often focuses on single sensory channels, limiting understanding of real-world perception.

Purpose of the Study:

• To investigate the origins and mechanisms of history effects in perceptual decisions.
• To explore how history effects transfer across different sensory modalities.
• To develop a multisensory framework for studying perception in naturalistic environments.

Main Methods:

• Utilizing a multisensory approach with combined visual-vestibular stimuli.
• Leveraging cross-modal transfer of history effects as a diagnostic tool.
• Manipulating response formats independently of sensory stimulation.

Main Results:

• History effects in perceptual decisions can be transferred across visual and vestibular modalities.
• This cross-modal transfer provides insights into shared processing stages.
• The experimental design allows for dissociation of sensory input and response output.

Conclusions:

• A multisensory approach is effective for dissecting the mechanisms of history effects.
• Shared processing stages likely underlie history effects in visual and vestibular perception.
• This framework advances our understanding of how recent history shapes perception in everyday multisensory environments.
